Question

A cell has a mutation that causes a shape change in a cell-surface receptor protein that binds a signaling molecule. What effect is this likely to have on that particular signal transduction pathway?

Answer 1

Mutations. Mutations have the ability to greatly impact the cell cycle. For example, mutations in the signal transduction pathway can prevent the cell from regulating its cell cycle. When the cell cycle is unregulated, it can result in unrestricted cell division that could lead to harmful conditions like cancer.
